<p class="MsoNormal"><span lang="EN-US" style="color:#1F497D">you could try to do a Delaunay triangulation of your points to get a surface representing the ground. You might have to project your points onto a plane since normally Delaunay triangulation works
only in 2d AFAIK. Once you have the ground, you can define additional points at the edges of the volume you want to consider, define lines and surfaces and finally the volume. Then you can do a mesh3D.<o:p></o:p></span></p>
